What is the area of a parallelogram if its length is x+4 and its height is x+3

lord [1]

Area of a parallelogram is:

$\sf A=bh$

Where 'b' is the base and 'h' is the height. Plug in what we know:

$\sf A=(x+4)(x+3)$

Distribute(multiply everything in the first parenthesis to everything in the second parenthesis):

$\sf x\times x=x^2$
$\sf x\times 3=3x$
$\sf 4\times x=4x$
$\sf 4\times 3=12$

So we have:

$\sf A=x^2+3x+4x+12$

Combine like terms(3x + 4x = 7x):

$\sf A=\boxed{\sf x^2+7x+12}$

How many solutions does the following have? Y = x - 1 & y - x = -9

n200080 [17]

Answer:

No solution

Step-by-step explanation:

y=x-1 and y-x=-9

1st make sure both equations are in slope intercept form

since the 2nd equation isn't, you change it by adding x to both sides and rewrite it as y=mx+b so

y-x=-9

+× +×

y=×-9

now you have y=x-1 and y=x-9

substitute the y with the other equation

x-1=x-9

subtract x from both sides since you can't have the variable on both sides

now you've got -1 = -9

and since that equation isn't true, it has no solution.
